relationship study of various palladium supported on charcoal (Pd/C) catalysts has been undertaken for the Heck reaction of aryldiazonium tetrafluoroborate with acrylates. The optimized protocol enables the cross-coupling with a low loading of palladium at room temperature in technical grade methanol. Although the catalyst could not be recycled at this time, measurement of the palladium content by inductively
对于四氟硼酸芳基重氮鎓与丙烯酸酯的Heck反应,已经进行了各种负载在木炭(Pd / C)催化剂上的钯的性能-活性关系研究。经过优化的方案可以在室温下以工业级甲醇与低负载的钯进行交叉偶联。尽管此时催化剂无法循环使用,但通过电感耦合等离子体质谱法(ICP-MS)对钯含量的测量表明,钯对溶剂和产物的污染较低,与均匀条件相比,该方法对环境更安全。
